D10077 - Reference, Mongo Setup

This chapter belong to third part tutorial, not related to zero system here, but we ignored all third part installing steps. For mongo db part, once you finished installing, you can set the configuration and start up shell script as following:

OS: MacOS 10.13.3
MongoConf: /usr/local/etc/mongod.conf

1. Conf File

You can set default mongo db configuration via conf up.god.file /usr/local/etc/mongod.conf, the content is as following:

  destination: up.god.file
  path: /Users/lang/Runtime/service-mesh/mongodb/logs/mongo.log
  logAppend: true
  dbPath: /Users/lang/Runtime/service-mesh/mongodb/db/
  port: 6017

2. Start Up

Then write executed script as following ( Authorization Enabled ) :

#!/usr/bin/env bash
mongod --auth --config /usr/local/etc/mongod.conf

When you started mongo db, you should see the logs as following:

Be sure you could see the segment security: { authorization: "enabled" }

3. Create Account

1 - connect to mongo db with mongo command:

➜  ~ mongo localhost:6017
MongoDB shell version v3.6.2
connecting to: mongodb://localhost:6017/test
MongoDB server version: 3.6.2

2 - switch default database admin

> use admin
switched to db admin

3 - database authorized and login:

> db.auth("admin","admin")

4 - switch to database ZERO_MESH

switched to db ZERO_MESH

5 - create user for ZERO_MESH database with following:

> db.createUser({ user:'zero_mongo',pwd:'zero_mongo',roles:[{role:'dbOwner',db:'ZERO_MESH'}]});
Successfully added user: {
    "user" : "zero_mongo",
    "roles" : [
            "role" : "dbOwner",
            "db" : "ZERO_MESH"

6 - check the results, please be sure _id contains the prefix of database name is not admin here.

> use admin
switched to db admin
> db.system.users.find({user:'zero_mongo'});
{ "_id" : "ZERO_MESH.zero_mongo", "user" : "zero_mongo", "db" : "ZERO_MESH", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "UO+X+9i/uAqGXQ2EIliRVg==", "storedKey" : "oK3WotUQHTs3dvpNeLHiYzTgP4w=", "serverKey" : "+Hgbv9XO2NRfRe7ZFa0DVsyRCJo=" } }, "roles" : [ { "role" : "dbOwner", "db" : "ZERO_MESH" } ] }

7 - database authorized with new created user

switched to db ZERO_MESH
> db.auth("zero_mongo","zero_mongo");

4. Summary

Then you can connect with some mongo client such as Compass to connect to this database, your mongo db has been configured successfully.

Step 1:

Step 2:
